Abstract

The invention discloses a leakage current detection method, device and equipment for alternating current and a storage medium. The method includes the following steps: collecting a leakage current analog signal at each sampling time, and converting the leakage current analog signal at the current sampling time into a sampled value of leakage current by analog-to-digital conversion; when a sampledvalue of leakage current is acquired, judging whether the total number of sampled values of leakage current in a storage queue reaches a preset number of samples per period; and when the total numberof sampled values of leakage current in the storage queue reaches the preset number of samples per period, acquiring the effective value of leakage current at the previous sampling time, and obtainingthe effective value of leakage current at the current sampling time according to the effective value of leakage current at the previous sampling time, the sampled value of leakage current corresponding to the earliest data in the storage queue and the sampled value of leakage current at the current sampling time. The technical problem that the existing leakage current detection method is slow indetection and cannot realize real-time detection is solved.

Description

technical field [0001] The invention relates to the field of power measurement, in particular to a method, device, equipment and computer-readable storage medium for detecting leakage current of alternating current. Background technique [0002] With the increasing number of industrial and commercial and household electrical equipment, there are more and more low-voltage electrical nodes. Due to the non-standard electrical equipment and wiring, or the aging of equipment, various safety accidents caused by leakage occur frequently. Social property and personal safety have brought huge losses. In order to prevent electric leakage from causing safe electricity accidents, it is necessary to carry out leakage protection on electrical equipment and power lines, and the detection of leakage current is an important part of leakage protection. It is necessary to re-acquire at least one complete cycle signal, and then calculate the leakage current value based on all the signals in at...
